A160T Hummingbird UAV Sets Hover Record

A DARPA
press release (PDF format) reports that the A160T
Hummingbird UAV has set a new world record for unrefueled rotorcraft
endurance by staying aloft for 18.7 hours during phase I test
demonstrations. It also set a new endurance record for UAVs in the 1,102
lbs to 5,511 lbs weight class. The flying robot, built by Boeing, is
powered by a gas-turbine engine. During the tests it carried a 300lbs
payload. The test flight was fully autonomous. The eventual goal is
to achieve flight times in excess of 24 hours. For more info on the
